This application is a continuation of U.S. application Ser. No. 17/155,939, filed 22 Jan. 2021, which claims the benefit of U.S. Provisional Application No. 62/964,559, filed 22 Jan. 2020, which is incorporated in its entirety by this reference.

TECHNICAL FIELD

This invention relates generally to the vehicle telematics field, and more specifically to a new and useful system and method for collision reconstruction in the vehicle telematics field.

BACKGROUND

In the event of a vehicular accident, a conventional action—in constructing an insurance claim, for instance—is to reconstruct the accident in order to determine such information as who and/or what is at fault as well as the extent of the damage.

Conventional methods for accident reconstruction are performed completely or nearly completely manually, and often with a very limited, unreliable, and/or inconsistent set of information. The most useful information with which to accurately and objectively assess the accident is currently conventionally unavailable to those reconstructing the accident, and even if a portion is available, it is difficult to collect and assess. Furthermore, the overall accident reconstruction process is conventionally slow and tedious, made up of highly manual, human-centric processes.

In a variation of a conventional accident reconstruction process (e.g., as shown in FIG. 8A), for instance, the process starts with an insurance company receiving a claim in response to the occurrence of an accident. Often days later, the driver is contacted, and an investigation into the factors involved in the accident (e.g., the involvement of another vehicle, the involvement of a pedestrian, towing of a vehicle, police involvement, etc.) begins, often when relevant and/or helpful information is already forgotten, now biased, or otherwise less reliable. A first notice of loss (equivalently referred to herein as a first notification of loss) is then produced, which assesses the overall magnitude and/or type of damage resulting from the accident. In an event that the accident only involves property loss, a trip to an auto body is prompted. In an event that the accident analysis is more complex, an investigation into potential fraud, manipulation of memory, and/or other causes for inaccurate information may be prompted. These investigations, however—in addition to being slow—are most often not precise and can be heavily biased as well as slow moving.

Thus, there is a need in the vehicle telematics field to create an improved and useful system and method for reconstructing vehicular accidents.

2. Benefits

The system and method for collision reconstruction can confer several benefits over current systems and methods.

First, in some variations, the system and/or method confers the benefit of easily and promptly accessing reliable and relevant information associated with a vehicular accident. In specific examples, for instance, the system and method leverage any or all of the following information associated with one or more vehicles involved in an accident and collected, at least partially, at a mobile device to make a quantitative assessment of the vehicular accident: location information, motion information, driver information, passenger information, circumstantial information, and/or any other suitable information. This can further function to remove or minimize the use of unreliable human accounts in the reconstruction of an accident. Additionally or alternatively, any or all of the information can be used to trigger a response and/or action to help a driver involved in a collision, such as a life-saving response (e.g., notifying emergency services, notifying the police, etc.), assistance in performing one or more tasks and/or eliminating one or more tasks typically required to be performed by the driver (e.g., by completing and/or assisting in and/or eliminating paperwork required by the driver's insurance company, by automatically recommending and/or contacting a body shop in response to a collision, etc.), and/or performing any other suitable functions.

Second, in some variations, additional or alternative to the first, the system and/or method confers the benefit of decreasing the time required to reconstruct an accident and subsequently the time required to produce one or more outputs (e.g., insurance claim, auto body work approval, etc.) associated with an accident. In specific examples, for instance, information associated with the accident is collected in real time or near real time (e.g., within seconds, within less than a minute, within less than an hour, etc.) from a mobile device associated with the accident (e.g., a driver's mobile phone), and used to at least partially assess the accident.

Third, in some variations, additional or alternative to those described above, the system and/or method confers the benefit of producing an accurate, easily interpretable output reconstructing the accident. In specific examples, for instance, the method produces an easy intelligible user interface (e.g., at a client application) and/or set of materials (e.g., slide deck, visuals, reports, etc.) with which insurance companies can view one or more parameters (e.g., G-forces, speeds, etc.) associated with an accident. Additionally or alternatively, the system and/or method can determine and/or autofill one or more sections of an insurance report, determine and/or autofill any or all of a claim adjustment, determine and transmit a set of parameters associated with the collision (e.g., as determined by a model and/or set of modules as described below) to an insurance entity, and/or can perform any other suitable functions.

Fourth, in some variations, additional or alternative to those described above, the system and/or method confers the benefit of partially or fully automating one or more processes related to collision detection and/or reconstruction. In preferred variations, for instance, the method is partially or fully implemented with artificial intelligence (e.g., machine learning and/or deep learning models, with machine learning and/or deep learning modules, etc.). Additionally, the system and/or method can function to continue to learn (e.g., be continuously retrained) from the continuously detected telematic data collected from drivers. In specific examples, the model used to process telematic information (and optionally other information), implements both traditional machine learning and deep learning processing, which improves performance of the model in automatically producing one or more parameters associated with the collision. In specific examples, the system and/or method confers the benefit of automatically initiating, performing, and/or verifying an insurance claim in response to a collision.

Additionally or alternatively, the system and method can confer any other suitable benefit(s).

No. 17/111,299, filed 3 Dec. 2020, each of which is hereby incorporated in its entirety by this reference.

The method 200 is preferably performed with a system 100 as described above, but can additionally or alternatively be performed with any other suitable system(s).

The method 200 preferably functions to automatically detect and reconstruct a collision, but can additionally or alternatively function to produce one or more outputs in light of a collision,

4.1 Method: Collecting a Set of Inputs S205

The method 200 includes collecting a set of inputs S205, which functions to collect information (e.g., data) with which to determine the occurrence of a collision and to reconstruct on or more features of the collision.

The set of inputs collected in S205 is preferably at least partially received from a set of one or more mobile devices, further preferably from one or more sensors of the mobile device, such as through a software development kit (SDK) and/or a client application executing on each of the set of mobile devices. Additionally or alternatively, information can be collected from the vehicle (e.g., through one or more sensors of the vehicle, through an on-board diagnostics port, etc.), devices external to a vehicle (e.g., road infrastructure devices such as cameras associated with a set of traffic lights), one or more users (e.g., observers), and/or any other suitable information sources.

The information is preferably, at least in part, collected continuously while the vehicle is being driven and optionally while the vehicle is not being driven (e.g., while parked). Additionally or alternatively, any or all of the information can be collected periodically (e.g., at regular intervals, at irregular intervals, at a predetermined frequency, etc.). The information is further preferably collected automatically in response to a trigger (e.g., detection of a nonzero vehicle speed to indicate the initiation of a trip), but can additionally or alternatively be collected in response to multiple triggers, collected in response to a user input (e.g., notification from a user that an accident has occurred) and/or permission, and/or otherwise collected.

S205 is preferably performed continuously throughout the method 200 and further continuously while the driver is driving, but can additionally or alternatively be performed once, multiple times, and/or any combination. S205 is preferably performed prior to S210 but can additionally or alternatively be performed prior to S220, after S210, prior to S230, after S230, and/or at any other suitable times. Further additionally or alternatively, an instance of S205 can be performed prior to S210 (e.g., wherein a collision is detected based on a first set of inputs) and after S210, wherein the second set of inputs and/or any or all of the first set of inputs is used to reconstruct the collision.

The information collected in S205 is preferably received at a processing system (e.g., remote computing system, mobile device computing system, processor of mobile device, etc.) and/or database of the system (e.g., as described above) for processing and/or storage, but can additionally or alternatively be received at any suitable location(s).

In the event of a collision, at least a portion of the information is preferably collected contemporaneously with the collision, such as during the collision, just prior to the accident, and/or immediately following the collision. In variations in which information is collected following a collision, the method 200 can optionally include overriding one or more triggers (e.g., vehicle speed below a predetermined threshold, vehicle reaching an ‘off’ state, detection of a vehicle malfunction, etc.) for ceasing data collection. In specific examples, for instance, a trigger normally associated with the end of a vehicle's drive (e.g., vehicle has stopped moving, vehicle has zero speed for a predetermined duration, etc.) is overridden in response to detecting an accident (such as through any or all of the processes described in U.S. application Ser. No. 15/243, 565, filed 22 Aug. 2016, which is incorporated in its entirety by this reference), the collection of information continues.

S205 can optionally include any or all of: marking, tagging, flagging, prioritizing, ranking, filtering (e.g., signals filtering, filtering to different locations, etc.), pre-processing, or otherwise adjusting the information collected in S210. In some variations, for instance, information collected contemporaneously with an accident is tagged for further (e.g., more detailed) processing.

The information collected in S205 preferably includes location information associated with the location and/or trajectory of the vehicle. This can include any or all of: geographical information (e.g., GPS coordinates), route information (e.g., vehicle is located at an intersection, vehicle is in an outside lane, vehicle is at a stop sign, etc.), a starting location of the vehicle's route, a destination of the vehicle (e.g., as an input into a navigation application, etc.), and/or any other suitable information. The location information is preferably collected from a GPS sensor of a mobile device of an individual inside the vehicle via an SDK operating on the mobile device, but can additionally or alternatively be otherwise received from any suitable source.

The information collected in S205 can additionally or alternatively include temporal information associated with the vehicle, such as any or all of: a time (e.g., associated with the occurrence of an accident), one or more temporal characteristics associated with (e.g., determined based on, derived from, etc.) a time (e.g., accident occurred during rush hour, accident occurred outside of rush hour, traffic level at the associated time, predicted activity of the user, etc.), and/or any other suitable information.

Further additionally or alternatively, the information collected in S205 can include vehicle information associated with one or more vehicles. The one or more vehicles preferably includes a vehicle involved in the accident, but can additionally or alternatively include a vehicle nearby the accident (e.g., associated with an observer), a vehicle unrelated to the accident (e.g., associated with the route, aggregated into a set of data, etc.), and/or any other suitable vehicles.

The vehicle information preferably includes movement information (equivalently referred to herein as motion information) associated with the vehicle, which refers to any data related to the position, velocity, and/or acceleration of any or all of the vehicles described above. In preferred variations, the motion information collected and/or determined based on information collected in S205 includes acceleration, velocity, and position information, but can additionally or alternatively include other motion information and/or a subset of this information (e.g., only acceleration).

Movement data can be collected from and/or associated with any one or more of: motion sensors (e.g., multi-axis and/or single-axis accelerometers, gyroscopes, etc.), location sensors (e.g., GPS data collection components, magnetometer, compass, altimeter, etc.), and/or any other suitable components. Such components are preferably arranged at a mobile computing device (e.g., smartphone, laptop, tablet, smart watch, smart glasses, medical devices, etc.) associated with a user (e.g., a vehicle driver), wherein the motion information of the mobile computing device is used to determine (e.g., equated to, based on orientation information of the mobile computing device, etc.) motion information corresponding to the vehicle in which the mobile computing device is located. As such, the movement data can optionally include orientation information from the mobile computing device (e.g., in east-north-up coordinates), wherein the orientation information is used to isolate and remove (e.g., subtract) movement of the mobile computing device relative to the vehicle, thereby enable movement of the vehicle relative to the earth to be determined and/or better approximated.

In some variations, for instance, S205 can include receiving one or more movement datasets collected at least at one of a location sensor and a motion sensor arranged within the vehicle, where the location sensor and the motion sensor are arranged at a mobile computing device positioned within the vehicle. Additionally or alternatively, the vehicle can include onboard sensors (e.g., speedometers, accelerometers, etc.) used in collecting movement data. For example, S205 can include collecting a movement dataset at at least one of a location sensor and a motion sensor of a vehicle (e.g., a vehicle that is being driven by the user). However, any suitable components associated with any suitable devices can be used in collecting movement data and/or data from which movement data can be derived. For example, S205 can include deriving movement data from visual data (e.g., deriving velocity from video taken by a smartphone's camera) and/or audio data (e.g., deriving motion from Doppler effects captured in data from the smartphone's microphone, etc.), as described in more detail below.

The vehicle information can additionally or alternatively include data from vehicle sensors such as OEM sensors and/or sensors mounted to and/or otherwise coupled to the vehicle, which can include any one or more of: proximity sensor data (e.g., radar, electromagnetic sensor data, ultrasonic sensor data, light detection and ranging, light amplification for detection and ranging, line laser scanner, laser detection and ranging, airborne laser swath mapping, laser altimetry, sonar, etc.), vehicle camera data (e.g., in-car cameras, exterior cameras, back-up cameras, dashboard cameras, front-view cameras, side-view cameras, image recognition data, infrared camera, 3D stereo camera, monocular camera, etc.), car speed, RPM data, odometer, altimeter, location sensor data (e.g., GPS data, compass data, etc.), motion sensor data (e.g., from an accelerometer, gyroscope, etc.), environmental data (e.g., pressure, temperature, etc.), light sensor data (e.g., from infrared sensors, ambient light sensors, etc.), fuel level (e.g., percentile-based, distance-based, low warning, etc.), fuel system status, oxygen sensor data, throttle position, gear data (e.g., drive, neutral, park, reverse, gear number, etc.), HVAC data (e.g., current temperature, target temperature, etc.), driving status (e.g., restricted features such as user inputs into control panel, unrestricted features, etc.), and/or any other suitable vehicle data. For example, vehicle sensor data can provide information on the status of a vehicle before/during/after an accident (e.g., by collecting airbag deployment data, ABS or other braking system data, engine temperature data, etc.). For example, S205 can include receiving a proximity dataset collected at a proximity sensor of the vehicle.

Vehicle sensor data (e.g., vehicle subsystem status data) can optionally partially or fully be collected via the vehicle's on-board diagnostics (OBD) port. For example, S205 can include using OBD-II Parameter IDs to request OBD data from a vehicle. In another example, S205 can include detecting deployment of an airbag through a communicable link with a vehicle. However, collecting vehicle sensor data through the OBD system can be performed in any manner and/or the S205 can be performed in absence of collecting information from an OBD port and/or vehicle sensor data can be collected in any other suitable ways.

In a first variation, the vehicle information collected in S205 and/or determined based on vehicle information collected in S205 includes any or all of: a vehicle location (e.g., in GPS coordinates), a vehicle speed (e.g., deceleration speed), a vehicle acceleration, a vehicle action (e.g., braking, accelerating, turning, maintaining a speed, etc.), a vehicle heading (e.g., forward, backward, particular heading angle, etc.), a type of vehicle (e.g., make of vehicle involved in accident), an airbag deployment parameter (e.g., as measured as a change in pressure in the vehicle cabin), a G-force/severity of an accident, a direction and/or location of impact, a stopping distance of the vehicle, and/or any other suitable information.

In specific examples, the information collected in one or more instances of S205 includes information which occurs in time after the collision (e.g., user's location after collision, etc.), which can be used, for instance, in evaluating one or more models and/or modules (e.g., as described below). In a particular specific example, for instance, the user's location after a collision is used to see where the user travels to (e.g., to see if user goes to an auto body shop, hospital, home, stays in middle of highway, etc.), which can function to determine any or all of: whether or not a collision occurred (e.g., at the collision detection algorithm, at the confidence module, etc.), whether or not the collision was severe (e.g., at the severity detection algorithm), whether or not fraud was detected (e.g., at the fraud module), and/or any suitable outputs.

The information collected in S205 can additionally include driver information, such as any or all of: historical information associated with the driver (e.g., prior history of collisions, prior history of fraud, riskiness of driver's driving behavior as represented in a driving risk score, etc.), a driver's attention and/or distraction level, an activity of the driver (e.g., texting), a driver score (e.g., safety score, risk score, etc.), a driver behavior (e.g., during accident, prior to accident, after accident, etc.), circumstantial information (e.g., driver had a long work day beforehand and was tired, driver was in an area he had never driven in before, etc.), intoxication level, and/or any other suitable information. Further additionally or alternatively, any other user information, such as passenger information, observer information, and/or any other information can be collected.

The information collected in S205 can further additionally or alternatively include environmental and/or circumstantial information (e.g., any or all of the auxiliary information described above) which characterize a driving environment of the vehicle, such as any or all of: a type of road (e.g., highway, residential, school-zone road, hospital-zone road, parking lot, one-way road, two-way road, number of lanes of road, etc.), environmental conditions at the time of driving (e.g., weather conditions, road conditions, time of day/amount of light, etc.), road conditions (e.g., paved surface, un-paved surface, smooth surface, pothole incidence, etc.), traffic conditions (e.g., traffic level), and/or any other suitable information.

The information collected in S205 can further additionally or alternatively include information directly related to a collision, such as any or all of: police reports, claims reports and/or any other information from an insurance entity, information related messages and/or calls and/or notifications at a mobile computing device of the user (e.g., indicating that user has called emergency services, indicated that user has called an auto body shop, indicating that user is responsive, etc.), and/or any other suitable information.

In a first variation of S205, all of the information collected is collected via an SDK of a set of one or more mobile devices, wherein at least one mobile device is associated with a vehicle involved in the accident.

In a second variation of S205, a first portion of the set of inputs is collected is collected via an SDK of a set of one or more mobile devices, wherein at least one mobile device is associated with a vehicle involved in the accident, and a second portion of the set of inputs is collected from any or all of: a processing system onboard and/or mounted to the vehicle, one or more stored databases (e.g., at the mobile device, at remote storage, etc.), an online source (e.g., weather source, traffic conditions source, etc.), and/or from any other suitable sources.

Additionally or alternatively, the set of inputs collected in S205 can include any other suitable inputs collected in any suitable ways from any suitable sources.

4.2 Method: Detecting a Collision and/or One or More Features of the Collision S210

The method preferably includes detecting a collision and/or one or more features of the collision S210, which functions to classify the set of inputs in S205 as corresponding to a collision (or not). Additionally or alternatively, S210 can function to determine (e.g., detect, classify, etc.) one or more features associated with a collision (e.g., severity, direction of impact, etc.), produce a set of outputs with which to perform S220, trigger an response (e.g., an emergency response), and/or can perform any other suitable functions.

S210 is preferably performed at a processing system (e.g., remote processor, processor of one or more mobile devices, etc.) and/or computing system (e.g., remote computing system), such as any of those described above in the system 100, but can additionally or alternatively be performed by any suitable component(s).

S210 is preferably performed in response to S205, but any or all of S210 (e.g., the collision detection algorithm) can additionally or alternatively be performed prior to S205 (e.g., to prompt collection of one or more inputs in S205) and/or at any other suitable times. Additionally or alternatively, S210 can be performed in parallel with and/or part of S220. Further additionally or alternatively, S210 can be performed multiple times throughout the method 200 (e.g., continuously, at a predetermined frequency, at a set of random intervals, etc.) and/or at any other suitable times.

S210 includes analyzing (e.g., assessing, processing, etc.) the information collected in S205, with a set of models no including a collision model (e.g., as shown in FIG. 1). The collision model preferably includes a set of one or more classifiers (e.g., as described above), further preferably a set of machine learning (e.g., traditional machine learning, deep learning, etc.) classifiers, such as any or all of the classifiers described above. Additionally or alternatively, any other suitable algorithms and/or models can be used in the collision model.

The collision model preferably receives as input at least a set of sensor inputs received in S205 (e.g., from a mobile device of the driver), such as any or all of: location information (e.g., GPS coordinates from a GPS sensor of the mobile device), acceleration information (e.g., from an accelerometer of the mobile device, from an inertial measurement unit [IMU] of the mobile device), pressure information (e.g., from a barometer of the mobile device to detect changes in pressure in the vehicle as resulting from airbag deployment, for instance), orientation information (e.g., from an IMU of the mobile device), and/or any other suitable sensor information. Additionally or alternatively, the collision model can receive sensor information from sensors independent of (e.g., offboard) the mobile device (e.g., from vehicle sensors, from environmental sensors, etc.), information other than sensor information (e.g., historical information, a risk score and/or prior driving behavior of the driver, environmental information, etc.), and/or any other suitable information.

The algorithms (e.g., classifiers) of the collision model can individually and/or collectively function to take into account and aggregate the multiple types of information sources collected above, which as previously described, are conventionally not available for reconstruction analyses. In examples, the algorithms of the collision model can function to take into account circumstantial driver information (e.g., duration of drive, driver risk score, driver's amount of phone use, driver distraction level, etc.), along with location and/or vehicle information (e.g., speed, direction, location, etc.) to detect a collision and/or determine one or more features of the collision.

The outputs of the algorithms can include and/or be used to determine any or all of: a binary output (e.g., binary classification, binary output determined based on a set of probabilities, etc.), a non-binary output (e.g., a non-binary classification, a multi-class classification, etc.), and/or any combination of outputs. Further additionally or alternatively, the algorithm outputs (or other outputs of the collision model) can include any or all of: parameter values (e.g., vehicle speed, vehicle acceleration, outputs from one or more dynamic equations, motion parameter values, etc.) such as those related to auxiliary information as described above and/or below, a set of parameters (e.g., weights) for use in implementing one or more modules in S220, and/or any other suitable outputs.

In a preferred set of variations, the algorithms in the collision model produce one or more probabilistic outputs, which can be used to make a set of one or more classifications (e.g., based on comparison with one or more probability thresholds, based on comparison with each other wherein the class/label associated with the higher probability is selected, as shown in FIG. 3, etc.), trigger S220 (e.g., in response to determining a collision has occurred), and/or be used as inputs in S220 (e.g., wherein any or all of the modules determine outputs based in part or in full on the probabilistic outputs). Additionally or alternatively, the outputs can be used, for instance, in triggering a response and/or for use in producing an output in S230 (e.g., a report, an insurance claim, etc.). The collision model further preferably calculates and/or passes along auxiliary information which is used by the set of modules to determine any or all of the module outputs. Additionally or alternatively, auxiliary information can be produced by other model(s), S210 can be absent of producing and/or interfacing with auxiliary information, and/or the model in S210 can be otherwise evaluated.

The set of algorithms preferably includes a collision detection algorithm (e.g., as described above), wherein the collision detection algorithm functions to detect that a collision has occurred. Additionally or alternatively, the collision detection algorithm can function to prompt the performance of other algorithms, trigger an emergency response, and/or can perform any other suitable functions. The collision detection algorithm preferably produces a binary determination (and/or enables a binary determination) of whether or not a collision has occurred (“yes” collision vs. “no” collision), such as through the determination of one or more probability values related to the occurrence of a collision (e.g., probability that a collision has occurred). In specific examples, for instance, these probability values can be used to make the binary determination (e.g., by comparing with a threshold, by selecting the higher of a probability of a collision having occurred and the probability of a collision having not had occurred, etc.). Additionally or alternatively, the collision detection algorithm can produce any other suitable outputs.

In preferred variations, the collision detection algorithm implements one or more machine learning algorithms, wherein the machine learning algorithms have been trained (e.g., as described below) to detect a collision. The machine learning algorithms preferably include both traditional machine learning and deep learning (e.g., as described above), but can additionally or alternatively include classical approaches, only traditional machine learning approaches, only deep learning approaches, and/or any other suitable approaches and/or combination of approaches. In specific examples, the collision detection algorithm is trained to detect a collision based at least on motion information associated with the vehicle (e.g., as collected at a mobile device of the driver inside of the vehicle), such as motion information corresponding to any or all of: a sudden acceleration of the vehicle, a sudden deceleration of the vehicle, a sudden change in direction of the vehicle's movement, a change in the vehicle's orientation, and/or any other suitable indicators of a collision. Additionally or alternatively, the collision detection algorithm can implement any or all of the processes, embodiments, and/or examples described in U.S. application Ser. No. 15/243,565, filed 22 Aug. 2016, which is incorporated herein in its entirety by this reference.

In a first specific example, the collision detection algorithm implements a gradient boosting machine algorithm (e.g., traditional machine learning gradient boosting machine), optionally in combination with a deep learning algorithm, configured to determine a classification of whether or not a collision has occurred.

The set of algorithms further preferably includes one or more collision feature detection algorithms, wherein the collision feature detection algorithms are configured to classify one or more features associated with the collision, such as, but not limited to, a severity of the collision (e.g., whether or not the collision is determined to be severe), a direction of impact to the vehicle, and/or any other suitable features. Additionally or alternatively, the collision feature detection algorithms can be configured to calculate one or more parameters associated with the collision, assign a ranking to a collision relative to other collisions, trigger an action and/or response, and/or can perform any other suitable functions.

The collision feature detection algorithms are preferably performed in response to (e.g., after) the collision detection algorithm, but can additionally or alternatively be performed contemporaneously with (e.g., in parallel with, partially overlapping with, fully overlapping with, etc.) the collision detection algorithm, prior to the collision detection algorithm (e.g., prior to a repeated instance of the collision detection algorithm), and/or at any other suitable times.

The set of collision feature detection algorithms can optionally include a severity detection algorithm, wherein the severity detection algorithm is preferably configured to determine a binary classification of whether or not the collision is severe, wherein a severe collision can refer to a collision, for instance, involving any or all of: an injury (e.g., of the driver, of a passenger, of a pedestrian, etc.), a fatality (e.g., of the driver, of a passenger, of a pedestrian, etc.), vehicular damage (e.g., totaled vehicle, minor damage, no damage, etc.), infrastructure damage (e.g., hit traffic sign), other factors, a combination of factors, and/or any other suitable classification of collision severity. Additionally or alternatively, the severity detection algorithm can detect a type of severity (e.g., fatality of driver vs. non-fatality of driver, fatality of passenger vs. non-fatality of passenger, totaled vehicle vs. non-totaled vehicle, etc.), a severity indication as indicated by a spectrum of severities, one or more parameter values, and/or any other suitable outputs.

The severity detection algorithm is preferably in the form of a machine learning algorithm, further preferably a gradient boosting machine algorithm and optionally a deep learning algorithm (e.g., as described above for the collision detection algorithm, different than that described above for the collision detection algorithm, etc.), but can additionally or alternatively include any other algorithms.

Additionally or alternatively, the set of collision feature detection algorithms can optionally include a direction of impact detection algorithm, wherein the direction of impact detection algorithm is preferably configured to classify the impact experienced by the vehicle in the collision. The direction of impact choices preferably include the following options (e.g., labels, classes, etc.), but can additionally or alternatively include any other suitable options: frontal impact, rear impact, broad side impact, side swipe impact, and rollover impact. Additionally or alternatively, the direction of impact detection algorithm can identify a location of impact on the vehicle (e.g., passenger door, passenger's side rear door, driver door, driver's side rear door, rear of vehicle, rear bumper, front of vehicle, front bumper, etc.), a direction of impact on another vehicle in the collision, and/or any other suitable parameters.

The output(s) of the direction of impact algorithm can include any or all of: a set of probabilities (e.g., associated with each option for direction of impact), a determined direction of impact (e.g., determined based on the set of probabilities, determined independently of the set of probabilities, associated with a particular confidence value, etc.), and/or any other suitable parameters and/or combination.

The direction of impact detection algorithm is preferably a classifier (e.g., multi-class classifier) in the form of a machine learning algorithm, further preferably a gradient boosting machine algorithm and optionally a deep learning algorithm (e.g., as described above for the collision detection algorithm, different than that described above for the collision detection algorithm, etc.), but can additionally or alternatively include any other algorithms.

In variations of S210 including multiple algorithms, the algorithms can be implemented in any or all of: series, parallel, and/or any combination. Additionally or alternatively, the algorithms can be any or all of: initiated automatically (e.g., in response to S205), initiated in response to a trigger (e.g., in response to detecting a collision, in response to the performance of and/or the outputs of another algorithm, in response to a temporal condition, etc.), initiated as prompted by a decision tree and/or lookup table, otherwise initiated, and/or initiated based on any combination of triggers and/or prompts.

Additionally or alternatively, the order in which any or all of the algorithms is performed can be determined based on a priority (e.g., predetermined priority, dynamically determined priority, etc.) associated with one or algorithms. In some examples, for instance, one or more algorithms which have the most time-sensitive outputs (e.g., a collision detection algorithm which prompts other algorithms and/or other processes such as emergency responses) are implemented first. In a particular example, the collision detection algorithm is implemented first, wherein the determination made by the collision detection algorithm can be used for any or all of: prompting the performance of other algorithms (e.g., collision feature algorithms) in S210; prompting the performance of one or more modules in S220; prompting one or more actions (e.g., notifying the driver at the driver's mobile device, notifying a passenger at the passenger's mobile device, etc.) and/or responses (e.g., initiating an emergency response, calling an ambulance, etc.) in S230; and/or prompting any other processes. In specific examples, for instance, in an event that a collision is detected in a collision detection algorithm of S210, the collision detection feature algorithms can be prompted in return, and in an event that a collision is determined not to be detected in an collision detection algorithm of S210, the method can be terminated and/or otherwise proceed (e.g., to S220, to S230, etc.). Additionally or alternatively, any or all of these processes can be performed independently of the outcomes of other algorithms, otherwise dependent on the outcomes of other algorithms, and/or can be otherwise performed.

Further additionally or alternatively, any or all of the algorithms can be performed: a single time, multiple times (e.g., as shown in FIGS. 4A-4B), and/or any combination. In collision detection, for instance, this can function to handle a tradeoff between the time required to detect a collision and the accuracy associated with the detection. Implementing this can function, for instance, to both quickly check for a collision in order to provide a quick response if needed and to utilize additional information which continues to be received (e.g., in response to repeated instances of S205) to confirm or deny this decision. In some cases, for instance, a driver's behavior after a collision can be used to come to a more accurate conclusion as to whether a collision occurred (e.g., if driver's vehicle stops in the middle of an intersection, if driver's vehicle is left on the highway, if driver calls a tow truck, if driver visits an auto body shop, if driver visits a hospital, etc.) or did not (e.g., if driver quickly continues driving along original route). In a preferred set of variations, the collision detection algorithm in S210 is performed multiple times (e.g., as shown in FIGS. 4A-4B), such as any or all of: a predetermined number of times (e.g., 2 times, 3 times, between 2 and 5 times, 5 times, between 5 and 10 times, 10 times, greater than 10 times, etc.); continuously (e.g., at a predetermined frequency); until a threshold condition and/or trigger condition is met (e.g., until confirmation that a collision has not occurred is determined, in response to a driver responding to a notification to confirm that he has not been in a collision, etc.); and/or any number of times. In specific examples, the collision detection algorithm is performed 3 times, first at 20 seconds after a potential collision is detected, again at 60 seconds after the potential collision is detected, and yet again at 120 seconds after the potential collision is detected. In alternative examples, this timing and number of times can be suitably adjusted.

Additionally or alternatively, the collision detection algorithm can be performed once, other algorithms can be performed multiple times, and/or the algorithms can be otherwise performed.

S210 can optionally include aggregating (e.g., combining, summing, averaging, combining according to an algorithm and/or equation and/or lookup table, etc.) any or all of the algorithm outputs. Additionally or alternatively, any or all of the algorithm outputs can remain independent.

In a first variation of S220, a set of machine learning classifiers are implemented which receive information collected in S205 and process the information to determine a set of probabilistic outputs related to any or all of: an occurrence of a collision, a severity of the collision, a direction of impact of the vehicle in the collision, and/or any other suitable outputs.

S210 can additionally or alternatively include any other processes. In some variations, for instance, S210 (and/or any other processes in the method) include determining one or more driving events, such as, but not limited to, any or all of: a hard brake event (e.g., in which the driver brakes a significant amount in a short distance and/or time, in which the driver brakes suddenly, etc.); a sudden acceleration event (e.g., in which the vehicle changes direction and/or speed suddenly and/or over a short distance or time); a mobile device usage event (e.g., indicating that the driver was using his or her mobile device while driving, a distraction event, etc.); a speeding event (e.g., indicating that the driver was speeding, indicating that the driver was speeding by at least a predetermined threshold, etc.); a turning event (e.g., indicating that the vehicle turned suddenly); and/or any other suitable driving events. Identification of any or all of these events can be used in reconstructions (e.g., as shown in FIGS. 9A-9G) of a collision, provided as an output to an insurance entity, and/or otherwise used in S230 or elsewhere in the method. In specific examples, for instance, determining events can be performed as described in U.S. application Ser.

4.3 Method: Reconstructing the Collision S220

The method 200 includes reconstructing the collision S220, which functions to determine features of the collision and/or information relevant to various entities (e.g., insurance entities, the driver, etc.) in light of the collision. As such, S220 can optionally function to determine who and or what is at fault for an accident, facilitate the production of an output (e.g., materials, emergency response, communication, etc.) associated with the accident in S230, and/or can perform any other suitable function(s).

S220 is preferably performed in response to S210 and based on the outputs produced in S210. Additionally or alternatively, S220 can be performed as part of S210, in parallel with S210, in response to S205, and/or at any other suitable time(s).

S220 is preferably performed with a processing system of the system 100 (e.g., the same processing system used in S210, a different processing system as that used in S210, etc.), but can additionally or alternatively be performed at any other suitable time(s). Additionally or alternatively, S220 can be performed multiple times during the method 200 (e.g., continuously, at a predetermined frequency, at random intervals, etc.) and/or at any other suitable times.

The confidence detection module preferably produces as an output a confidence parameter (e.g., confidence value, confirmed “yes” or “no” determination, etc.) associated with the determination that a collision has occurred, but can additionally or alternatively produce any other outputs.

In variations in which the collision detection algorithm is performed multiple times, the confidence detection module can optionally be performed multiple times, such as each time the collision detection algorithm is performed. Additionally or alternatively, the confidence detection module can be performed once (e.g., after the last iteration of the collision detection algorithm) and/or otherwise performed.

Additionally or alternatively, the confidence module can be performed multiple times (e.g., as described for the collision detection algorithm above) independent of how many times the collision detection algorithm is performed, a single time, a dynamically determined number of times (e.g., continuously until a threshold confidence level is reached, continuously until the confidence falls below a threshold and the method is terminated, etc.), and/or any other number of times.

The set of modules further preferably includes a severity module (equivalently referred to herein as a severity detection module), which functions to determine a severity associated with the collision. This can in turn function to help an insurance entity assess the collision (e.g., perform a claim adjustment), help the driver get properly reimbursed, inform the driver and/or other entities of next steps, recommend an appropriate body shop to the driver depending on the extent of the damage, call an ambulance (e.g., automatically by the processing system, from the user's mobile device, etc.), call a tow truck (e.g., automatically by the processing system, from the user's mobile device, etc.), and/or can function to perform any other suitable functions.

The severity module is preferably performed after (e.g., and offline, and online, etc.) the confidence detection module, and optionally in response to a request from one or more entities, but can additionally or alternatively be performed at any suitable time(s).

The severity module is preferably a machine learning model (e.g., traditional machine learning, deep learning, etc.), further preferably a regression model, but can additionally or alternatively include any other learned models, classical rule-based models (e.g., mappings), and/or any combination.

The severity module can produce any number of outputs, such as, but not limited to, any or all of: one or more scores (e.g., severity score, particular type of severity score, etc.), an indication of whether or not physical damage to the vehicle has occurred and/or is suspected to have occurred (e.g., fender bender damage, more serious damage, totaled vs. not totaled, estimated cost of repairs, property damage only [PDO] conclusion, etc.); an indication of whether or not injury to a driver and/or passenger and/or pedestrian has occurred and/or is suspected to have occurred (e.g., fatal injury, minor injury, no injury, etc.), and/or any other suitable outputs. The outputs for this module (and/or any other module) can be any or all of: quantifiable (e.g., severity values), qualitative (e.g., binary, ranking, etc.), any other output, and/or any combination.

Additionally or alternatively, the set of modules can be absent of a severity module and/or can include any other modules.

The set of modules further preferably includes a direction of impact detection module, which functions to determine the direction of impact of the vehicle associated with the driver (and/or another vehicle in the collision). This can, in turn, function to determine if the driver is at fault in the collision (e.g., if the driver has frontal damage indicating that he or she rear ended a vehicle).

The directions of impact preferably include those described above, but can additionally or alternatively include any other directions of impact.

The direction of impact module is preferably performed after (e.g., and offline, and online, etc.) the confidence detection module, and optionally in response to a request from one or more entities, but can additionally or alternatively be performed at any suitable time(s).

The set of modules preferably includes a fraud module, wherein the fraud module is configured to detect and/or determine (e.g., determine a perpetrator of, determine a type of, etc.) fraud associated with the collision. The fraud can be associated with fraud in which the driver is the victim, fraud in which the driver is the perpetrator, and/or any combination. The fraud can include, for instance, any or all of: a staged auto accident (e.g., driver forced another driver into a collision, driver braked suddenly to have driver behind rear end him, driver suddenly accelerated to hit another vehicle that he had motioned in, swoop and squat staged accident, drive down staged accident, panic stop staged accident, sideswipe staged accident, etc.); a misrepresentation of damages (e.g., extra damages claimed after collision); an uninsured driver being covered for by an insured passenger (e.g., as detected based on the driver's driving history and/or driving behavior and/or driving style); and/or any other fraudulent activities.

The fraud module preferably detects fraud based on a classical, rule-based model, but can additionally or alternatively implement one or more machine learning models (e.g., traditional machine learning, deep learning, etc.), and/or any other processes.

The fraud module is preferably performed after (e.g., and offline, and online, etc.) the confidence detection module, and optionally in response to a request from one or more entities (e.g., insurance company, police, etc.), but can additionally or alternatively be performed at any suitable time(s).

In some variations, the fraud module can include collecting information (e.g., in S205, after the collision, etc.) associated with another driver involved in the collision (and/or any other users such as passengers and/or pedestrians), which can function to bolster the outputs of the fraud module (e.g., by looking into another driver's behavior involved in crash).

The fraud module can produce any number of outputs, such as, but not limited to, any or all of: one or more probabilities (e.g., that the driver was involved in fraud, that another driver was involved in fraud, etc.), an identification of an individual and/or individuals involved in fraud, a confidence value (e.g., associated with a fraud determination), a type of fraud suspected, and/or any other suitable outputs.

Additionally or alternatively, the set of modules can be absent of a fraud detection module and/or can include any other suitable modules.

In a specific example, additional or alternative to the first, the set of modules are organized into a set of temporal groups, wherein the 1^(st) group includes the confidence module and is performed first (e.g., to reduce the time needed to elicit an emergency response) and the 2^(nd) group includes remaining modules and is performed at one or more later times (and optionally offline and/or in response to the request from an entity and/or once additional information such as the user's future location is collected).

In a third example, additional or alternative to the above examples, each of the modules receives the same set of outputs from S210 as inputs. In an alternative examples, any or all of the modules can receive different inputs relative to each other.

Additionally or alternatively, S220 can include any other processes and/or be otherwise performed.

4.4 Method: Producing an Output Based on the Reconstruction S230

The method 200 preferably includes producing an output based on the reconstruction S230, which functions to present a set of one or more features of an accident to a user or group (e.g., insurance agent, legal entity, law enforcement personnel, etc.), thereby providing key insights regarding the accident to create actionable insight. Additionally or alternatively, S230 can function to train one or more models and/or modules, predict and/or prevent the occurrence of an accident (e.g., through a notification to a driver in an accident-prone environment), and/or perform any other suitable function(s).

The output is preferably produced in response to S220, further preferably in response to processing the modules in S220, but can additionally or alternatively be produced in response to S210 (e.g., based on one or more classifiers), in response to a user request, upon confirmation of an accident, upon request by an entity, throughout the method 200, and/or at any other suitable time(s) and in response to any suitable triggers during the method 200. In some variations, for instance, data presented in the reconstruction output includes the outputs of one or more modules, auxiliary information (e.g., the vehicle speed just prior to the collision and a set of gravitational force equivalent [g-force and/or G-force] values involved in the collision) produced in S210 and/or prior to S210, optionally outputs from one or more classifiers in S210, and/or any other information produced at any suitable times during the method 200. In additional or alternative variations in which S230 involves the creation of an insurance claim, the insurance claim can be triggered and/or created and/or verified throughout the method 200.

The reconstruction output can include any or all of: a report/document (e.g., typed report, display, presentation, slide deck, video, audio recording, insurance claim, auto body report, etc.); a visualization (e.g., animated visualization of collision) such as a collision reconstruction dashboard (e.g., as shown in FIGS. 9A-9G); a score (e.g., updated driver score, updated route score such as a route risk score, etc.); a notification (e.g., text message, email, etc.); a communication (e.g., an automated call to an emergency responder, an automated call to the driver, etc.); and/or any other suitable output(s).

In some variations, the reconstruction output includes any or all of an insurance claim (e.g., as shown in FIG. 8B), wherein the method can include any or all of: triggering the creation of (e.g., initiating) a claim (e.g., in response to detecting a collision, in the form of an FNOL, etc.); updating a claim with additional information received, such as through repeated instances of S205 (e.g., subsequently identified locations and/or trips of the driver, follow-up with driver such as through notifications/messages and/or calls, etc.); accessing detailed collision information (e.g., collected in S205, determined throughout the method 200, etc.); producing a claim and/or claim recommendation based on any or all of the above; and/or any other suitable processes. In such variations, any or all of the information (e.g., collision information, historical driver data, etc.) in the method 200 can optionally be shared with an insurance entity, such as through any or all of: webhooks, APIs, and/or any other suitable processes and/or tools.

In a first set of examples of creating an insurance claim, the method includes automatically (e.g., zero touch/zero-click) and/or partially automatically (e.g., one touch) performing a claim registration process (e.g., as shown in FIG. 8A), which functions to automatically notify the driver's insurer that the driver was involved in a collision and/or to automatically create a claim in the insurer system. This can confer a benefit to the driver of not having to initiate this process himself or herself. This can also confer any number of benefits to claims adjusters (e.g., human claims adjusters, bots, etc.), such as, but not limited to, any or all of: enabling the claims adjuster to retrieve data associated with a driver (e.g., who has reported a claim) such as historical driving data (e.g., to be used for further analysis to identify a risk associated with the driver) and/or collision data; and/or any other benefits. Automatically notifying the insurer can optionally be performed with one or more third party applications and/or other third party tools (e.g., third party client applications executing on the user's mobile device and in communication with an SDK and/or application programming interface [API] collecting any or all of the inputs in S205) such as an insurance carrier application and/or tool configured to receive inputs from the system 100, the method 200, and/or from the user. In a particular specific example, the claim registration process is a one touch process in which the driver enters inputs (e.g., severity of collision input, choice or whether to report a claim or ignore it, etc.) into an insurance carrier application, wherein in response to the inputs, the insurance carrier application can optionally retrieve data associated with the collision and/or otherwise trigger a claim generation process. In another particular specific example, a third party tool can automatically retrieve data associated with the collision (e.g., from the SDK, from another client application, from storage, from a remote computing system and/or remote server, etc.), wherein the third party tool is responsible for creating the claim.

The reconstruction output can additionally or alternatively trigger one or more actions and/or responses, such as any or all of: the contacting of emergency assistance (e.g., police, ambulance, hospital dispatch, etc.); the contacting of the driver (e.g., through notifications as depicted in FIGS. 6A-6B, through notifications as depicted in FIGS. 7A-7B); the determination and/or adjustment of one or more insurance calculations and/or hypotheses (e.g., claims adjustment, determination of who is at fault, determination of damage extent of vehicle, initiating a FNOL report, etc.); and/or any other suitable actions and/or responses.

S230 can additionally or alternatively include determining (e.g., training) one or more models based on any or all of the outputs produced in the method, such as an insurance model (e.g., to automatically produce insurance outputs) and/or any other suitable models.

Additionally or alternatively, S230 can produce one or more insights (e.g., based on aggregated collision information) related to collisions, such as which factors contribute to (e.g., correlate with) collisions and/or how factors contribute to collisions, wherein the factors can include, for instance, any or all of: region in which the driver is driving (e.g., geographical region, road type, etc.), demographic information of driver (e.g., gender, age, size, etc.), vehicle information (e.g., vehicle make/model, vehicle size, etc.), and/or any other suitable information. In specific examples, for instance, data collected in the method indicating that a particular vehicle make/model has a particularly high incidence of frontal damage (e.g., due to side swiping other vehicles) can be used to determine that said vehicles have a particularly large blind spot.

S230 can additionally or alternatively be used to determine and/or update one or more scores associated with any or all of: a driver (e.g., through updating a driver risk score in an event of a collision), a road segment and/or road type, and/or any other suitable information. In some variations, for instance, S230 is used to update the risk score associated with particular road segments (equivalently referred to herein as route segments) associated with collisions (e.g., any collisions, collisions above a predetermined threshold, collisions above a predetermined threshold relative to number of miles driven on road segment, etc.). In specific examples, for instance, the risk associated with a route segment as determined in U.S. application Ser. No. 17/111,299, filed 3 Dec. 2020, which is incorporated herein in its entirety by this reference, can be updated based on any or all of the outputs determined in the method 200.

In a first set of variations, S230 includes generating a presentation productized as a UI for a user and/or entity, such as an insurance firm, the driver, law enforcement personnel, and/or any other user or entity.

In a second set of variations, S230 includes generating a report as part of a service for a user or entity, such as an insurance firm, the driver, law enforcement personnel, and/or any other user or entity. In specific examples, S230 includes providing a report to a claims adjuster which functions to ensure that the claim is commensurate with the collision.

In a third set of variations, S230 includes triggering an emergency response based on the output of the confidence module in S220 and/or any or all of the other modules.

In a fourth set of variations, S230 includes triggering an emergency response based on the output of the collision detection algorithm in S210 and/or any or all of the other algorithms.

Additionally or alternatively, S230 can include any other suitable processes.

4.5 Method: Training One or More Models and/or Modules

The method 200 can optionally include training any or all of the models and/or modules described above (e.g., as shown in FIG. 5), which can function to enable full or partial automation of any or all of the models and modules, improve the performance of any or all of the models and modules, enable any or all of the models and modules to continue to learn based on new and/or continuously collected data, and/or can perform any other suitable functions.

The training can be performed at any or all of: prior to S205, prior to S210, prior to S220, prior to S230, after S230 (e.g., as part of a retraining and/or updating of any or all of the modules and/or models), and/or at any other suitable times. Additionally or alternatively, training can occur multiple times during the method and/or the method can be performed in absence of training and/or retraining.

In some variations, a first training of one or more models and/or modules is performed prior to the method 200, wherein any or all of the trained models and/or modules is updated (retrained) based on the information collected in the method 200 and any or all of the outputs determined based on the information.

The information used to train the models and/or modules preferably includes historical data collected from previous drivers, such as any or all of the set of inputs collected in S205. The historical preferably includes at least sensor data collected from the drivers, further preferably at mobile devices (e.g., smartphones) associated with the drivers, and optionally any or all outputs indicating whether or not a collision occurred (e.g., outputs produced in S230, model outputs, module outputs, etc.) such as any or all of those described in the method (e.g., location and/or behavior information of the drivers post collision, driver confirmation in response to sending the driver a notification, etc.) and/or any other suitable data (e.g., from contacting drivers after collision for follow-up, from receiving confirmation from drivers regarding a potential collision, from insurance reports, from police reports, from auto body shop receipts, from interviews with any entities, etc.).

The information used to train any or all of the models and/or modules can additionally or alternatively include crash test data (e.g., to correlate sensor data with different types of collisions and/or collision features such as severity and/or direction of impact, etc.), data from one or more OBD ports of the vehicle and/or from one or more OEM components (e.g., during crash tests, on the road, etc.), and/or any other suitable information.

The training can additionally or alternatively include any number of human-in-the-loop analyses (e.g., during supervised learning), which can function, for instance, to implement human knowledge and/or other outside information—such as any or all of: police reports generated after accidents, insurance claims generated after accidents, auto body information generated after accidents, fraud characteristics, and/or any other suitable information—to train for accurate and useful classifications.

Additionally or alternatively, the training can include any other suitable processes.
